Liberty County authorities have charged the mother of two girls with a state jail felony after they were found locked in a room Saturday.

According to a news release issued by the Liberty County Sheriff's Office, Brandy Dominguez is charged with felony "abandonment/endangering a child by criminal negligence."

Dominguez' daughters, 2-year-old twins, were discovered by federal probation officers locked naked without food or water in a room that "smelled strongly of human waste," according to authorities. The officers were checking up on Dominguez, who was on pretrial release at the time in a human trafficking case.

Dominguez was not home when authorities showed up at the residence Saturday morning around 9 a.m. Additional investigation had to be done before bringing charges against her, said sheriff's department spokesman Capt. Ken DeFoor. Dominquez' sister, Amy Castillo was jailed on the similar charge Saturday. Her bond was set at $5,000
